About the Led spot old PCB

Led spot old is an open source STM32 PCB design by ervanalb, published on GitHub. It is a 4-layer board measuring 50 × 50 mm, with 45 components from 27 distinct parts.

Its main chip is the STM32F030-20, from the STM32 family. Other key parts include the LM2594-HV, 2CH-TVS, ISL83485IBZ and TPS92511. By type, the board carries 12 resistors, 11 capacitors, 7 ICs, 6 diodes, 4 inductors and 3 connectors.

From the project

Light control protocol

Lux is a protocol for the transmission of power and data from a host device to one or more nodes. It is capable of data rates approaching 3 megabits per second and supplying 30 Watts of power over distances of up to 100 feet. It is designed to be easy to implement and uses low-cost cabling and connectors.

Lux was designed as a lighting control protocol, specifically for LED strips. But, it generalizes nicely to any sort of automation on a small to medium scale.

Led spot old: common questions

What microcontroller does the Led spot old use?

The Led spot old is built around the STM32F030-20, from the STM32 family.

How big is the Led spot old PCB?

The Led spot old measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Led spot old?

45 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Led spot old design files?

From the ervanalb/lux repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Led spot old design in my own project?

The repository has no license, so all rights stay with ervanalb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Led spot old without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
